Copyleft symbol

At this time there is no copyleft symbol in the Unicode character encoding standard. Some methods consist in using the copyright symbol and apply a symmetry on it. Here is how.


<p><span class="copyleft">&copy;</span> Copyleft ...</p>


.copyleft {
    display: inline-block;
    -moz-transform: scaleX(-1);
    -o-transform: scaleX(-1);
    -webkit-transform: scaleX(-1);
    transform: scaleX(-1);
    filter: FlipH;
    -ms-filter: "FlipH";

Note that I prefer writing Copyleft next to the symbol, because it is still semantically considered as a copyright one. Also, a lot of old browsers may not display it correctly.
